摘要
为实现高地温隧道施工环境的有效控制,文章采用ANSYS Fluent软件建立三维数值模型,系统研究了不同通风风速(0.5~3.0m/s)对隧道内部温度分布的影响规律。研究表明,风速2.0m/s时可达到最优运行效果,温度降幅10.8℃,系统功率62.4kW,温度场标准差1.6℃。该研究可为高地温隧道通风系统设计和运行优化提供参考。
In order to realize the effective control of the construction environment of the tunnel with high ground temperature,this paper uses ANSYS Fluent software to establish a three-dimensional numerical model,and systematically studies the infuence law of 0.5一3.0m/s different ventilation wind speed on the internal temperature distribution of the tunnel.The study shows that the optimal operation effect can be achieved when the wind speed is 2.0m/s,and the temperature reduction is 10.8℃,the system power is 62.4kW,and the standard deviation of the temperature ficld is 1.6℃.This study can provide a reference for the design and operation optimization of high geothermal tunnel ventilation system.
